In order to provide theoretical basis for application of the ectopic microbial fermentation bed, the efficiency and quality of the ec-topic microbial fermentation bed in processing piggery waste were evaluated by measuring the changes of physicochemical and environmental factors and the absorption of piggery wastewater. The results showed that the fermentation temperature of the filler maintained above 40 ℃ for up to 48 days and the highest fermentation temperature was 66 ℃. The alkaline environment and the...
